Alternatives to Platform Screen Doors

Instead of installing platform screen doors for MRT stations, there are flashier alternatives. Effectiveness is not guaranteed, except in terms of dramatic terms.

It is not necessary to install complex door mechanisms that open with each aligned train carriage. My research finds that massively electrified fences have a greater deterrent effect against people attempting to commit suicide by jumping onto the train tracks in the face of oncoming trains. Not only does it serve as a physical barrier, it also serves as an active barrier! A further benefit is that it can coral recalcitrant idiots that refuse to line properly for the trains. Of course, some may ask how people may board the trains with the electrified fences in play; it is obvious, simply disable the electric supply to allow people to climb the fence when the trains arrive!

Another great idea is to line the platform with fountains dispensing vertical columns of fire. With this feature, commuters can barbecue food while waiting for the next train to arrive. The columns of flame also serve as cheap lighting during the evening. One crucial point to note while implementing this system is to ensure that the flames are turned all the way up, otherwise people may actually land on the train tracks while not being totally incinerated. We don't want people to die after being crushed by oncoming trains, do we?
